Overview
The Sontek FlowTracker2 ADV probe can be used in the field with the handheld display, or it can be used in the lab with direct PC connection. The ADV’s acoustic probe and processing electronics are housed in one small, lightweight, easily maneuverable unit, and the acoustic head has an optional, integrated pressure (depth) sensor.

Mechanics
Depth data are even correctable for dynamic pressure (Bernoulli) and altitude effects using SonTek’s patent-pending method. Setup of the probe and PC software is simple and mistake-proof. Just connect the cables between the probe and a laboratory PC or laptop, check a few settings, and press the “Start Logging” button. Data are output directly to a .CSV file that is immediately ready for use in the project, model, or database as required.

Questions & Answers
What is the purpose of the optional depth sensor?
During a discharge measurement, a typical user will read the water depth from wading rod markings. With a the integrated depth sensor, water depth can be measured automatically, reducing human error in the field and providing increased accuracy.

Three Decades of Research at Acton Lake

A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries

Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.
